| Abstract: | Generalized Rice process covers fading from the heaviest single-sided Gaussian process to the fading that is lighter than the Rice process.It has better performance than other fading channel models.This paper studies bit error rate (BER) performance of digital signals through a generalized Rice channel.Average BER of coherent binary phase shift keying ( BPSK),coherent binary frequency shift keying (BFSK),differential binary phase shift keying (DBPSK),and non-coherent BFSK detection schemes for slowly fading non-frequency-selective channels is derived.Influence of all parameters in the generalized Rice model on average BER is investigated. |

| Keywords: | fading channel channel model generalized Rice process bit error rate (BER) |
